Install: brew install aws-es-proxy

About:
aws-es-proxy is a lightweight proxy server that enables standard HTTP clients to communicate with AWS Elasticsearch domains. It automatically handles AWS Signature Version 4 signing, which is required by AWS but not supported by most generic HTTP tools. This allows you to use curl, Postman, or other REST clients with your secured Elasticsearch cluster without complex authentication setups.

Key Features:

Automatic AWS Signature Version 4 signing
Works with any HTTP client (curl, browsers, GUI tools)
Simple command-line interface
Supports all AWS regions and Elasticsearch domains
Lightweight and easy to deploy

Use Cases:

Debugging Elasticsearch queries using curl or browser
Integrating Elasticsearch with tools that lack AWS auth support
Testing API endpoints before implementing signing in applications
Providing temporary access to developers without AWS credentials

Alternatives:

aws4signer – Library-based solution requiring code integration vs proxy approach
elasticsearch-js – Official client with built-in AWS auth vs generic HTTP tool limitation
nginx with auth module – Complex setup vs simple single-binary proxy
